|
||
|
|
<div><p>A <dfn class="term">schema</dfn> provides a logical grouping
|
||
|
|
of SQL objects.</p>
|
||
|
|
<p>A <dfn class="term">schema</dfn> consists of a library, a journal, a journal receiver,
|
||
|
|
a catalog, and optionally, a data dictionary. Tables, views, and system objects
|
||
|
|
(such as programs) can be created, moved, or restored into any system library.
|
||
|
|
All system files can be created or moved into an SQL schema if the SQL schema
|
||
|
|
does not contain a data dictionary. If the SQL schema contains a data dictionary
|
||
|
|
then:</p>
|
||
|
|
<ul><li>Source physical files or nonsource physical files with one member can
|
||
|
|
be created, moved, or restored into an SQL schema.</li>
|
||
|
|
<li>Logical files cannot be placed in an SQL schema because they cannot be
|
||
|
|
described in the data dictionary.</li>
|
||
|
|
</ul>
|
||
|
|
<p>You can create and own many schemas. The term <dfn class="term">collection</dfn> can
|
||
|
|
be used synonymously with <dfn class="term">schema</dfn>.</p>
